General-Purpose Polarizers
These are polarizing-film type Polarizers sandwiched between protective cover plates: UV grade fused silica for the UV series, and grade A glass for the visible and infrared series.

Our 15 mm series are mounted in our standard black-anodized cell, l"dia x 0.3” thick. A white line scribed on the diameter of one face of the cell indicates the polarizing axis of the plate. 2" series are available as the cemented sandwich, or optionally mounted in our H-51-64 Cell. These can only be used with low power lasers. These cannot be used with high power lasers or in proximity with heat sources such as xenon or other lamps.

POLARIZING BEAMSPLITTERS
Our prism-cube Polarizing Beamsplitters consist of our AD-Series right-angle prisms cemented together with dielectric coatings on all surfaces. Because these are cemented, they cannot be used with high-energy lasers which may damage the cemented interface. The p-polarized component is transmitted and the s-polarized is reflected at 90°. Extinction ratio of the transmitted p-component and reflected s-component is >2000:1.

Walk-Off Polarizers
Walk-Off Polarizers are especially useful in fiber-optic applications to separate light of varying State of Polarization (SOP) into its S and P polarized components. These precision polished calcite blocks internally separate an input beam into the two polarized beams by 6° 14', yielding a 1:10 ratio of separation-to-length at output. It is possible to double the separation by putting two units in series. To maintain complete separation at output of the S and P beams, do not exceed Maximum Beam Diameter at input. Walk-Off Polarizers are available uncoated, or optionally with AR on both faces. Specify l when ordering. For applications requiring larger beams or greater separation, contact OFR.
